The authors proposed a new calculation method (direct method) which makes it possible to obtain the profile of a worm shaped tool or a form grinding wheel which can produce the required profile of helical gears within a very short period of computation time even when a micro-computer is used. In a generating motion between the worm shaped tool and the helical gear, three dimensional movements of the points on the cutting-edge or the surface of the tool (grinding wheel) were directly converted into the corresponding two dimensional movements without calculating the profile of the basic rack of the gears being ground. The required cutting-edge profile was obtained from a series of points which satisfy the condition required to make the enveloped curve (given tooth profile). Using the same method, the generated tooth profiles could be calculated even when the profile of the tool is arbitrarily given. This new method for calculating the profile is applicable to the almost manufacturing system of cylindrical gears.
